Native CDP browser automation reference. Headless/headed Chrome control, screenshots, JS evaluation. (/browser-cdp, browser automation, cdp, scraping).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Native Browser Automation (CDP) Built-in browser control via Chrome DevTools Protocol — no Node.js, no Playwright, pure Rust. ## Tools | Tool | Required | Optional | What | |------|----------|---------|------| | `browser_navigate` | `url` | `headless` | Navigate to URL | | `browser_click` | `selector` | — | Click element by CSS selector | | `browser_type` | `text` | `selector` | Type text into input | | `browser_screenshot` | — | `selector` | Screenshot (returns file path) | | `browser_eval` | `script` | — | Execute JavaScript | | `browser_content` | — | `selector`, `text_only` | Extract text/HTML | | `browser_wait` | — | `selector`, `timeout_secs`, `delay_secs` | Wait for element or delay | | `browser_find` | — | `pattern`, `mode`, `limit` | Inventory (no `pattern`) or find elements | ## Shadow DOM Selector resolution is shadow-DOM aware by default — nothing to enable. | Path | Open shadow roots | Closed shadow roots | |------|-------------------|---------------------| | `browser_find` modes `css`, `text`, `aria`, and the no-pattern inventory | Searched; hits are marked `[shadow]` | Not enumerable — `el.shadowRoot` is `null` for a closed root by spec | …

How to install
mdr add opencrabs/opencrabs/browser-cdp@sha256:bfc13dd2688b63cdThe line at the top of this page pins the label git:20260916.5d77e6c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
